Built-In Positioning Function/Program Supported 200 V Class (7 Kw Or Less); Built-In Positioning Function/Program Supported 100 V Class (0.4 Kw Or Less) - Mitsubishi Electric MELSERVO-J2S Series Transition Handbook

Part 7: Common Reference Material

2.1.3 Built-in positioning function/program supported 200 V class (7 kW or less)

The following table shows comparison of the MR-J2S series and MR-J4 series dimensions. The height and
width of the MR-J4 series are the same or smaller than the MR-J2S series basically. The depth is larger for
the 400 W and 600 W capacities. The replacements for 1 kW or less capacity types are possible using the
same mounting holes. The number of mounting screws is different for the 2 kW and 3.5 kW capacities, and
the mounting screw distance is different for the 5 kW to 7 kW capacities.

2.1.4 Built-in positioning function/program supported 100 V class (0.4 kW or less)

The following table shows comparison of the MR-J2S series and MR-J4 series dimensions. The height and
width of the MR-J3 series are the same or smaller than the MR-J2S series. The depth is larger for the 400 W
capacity. The mounting dimensions are interchangeable.
